Security for industrial automation and control systems – Part 2-4: Security program requirements for IACS service providers - Edition 1.0
 N 62443-2-4

Annotation

This part of IEC 62443-2-4 specifies requirements for security capabilities for IACS service providers that they can offer to the asset owner during integration and maintenance activities of an Automation Solution.

NOTE 1 The term "Automation Solution" is used as a proper noun (and therefore capitalized) in this part of IEC 62443 to prevent confusion with other uses of this term.

Collectively, the security capabilities offered by an IACS service provider are referred to as its Security Program. In a related specification, IEC 62443-2-1 describes requirements for the Security Management System of the asset owner.

NOTE 2 In general, these security capabilities are policy, procedure, practice and personnel related.

NOTE 3 The term "process" in BPCS may apply to a variety of industrial processes, including continuous processes and manufacturing processes.

NOTE 4 Clause 4.1.4 describes profiles and how they can be used by industry groups and other organizations to adapt this International Standard to their specific environments, including environments not based on an IACS.

NOTE 5 Automation Solutions typically have a single control system (product), but they are not restricted to do so. In general, the Automation Solution is the set of hardware and software, independent of product packaging, that is used to control a physical process (e.g. continuous or manufacturing) as defined by the asset owner.
